FIBER-CLEANING MACHINE.

Specification of Letters Patent.

Application filed. November 22, 1905. Serial Ne. 288,523.l I

To all whom 'it 'may concern: Be it known that I, AXeEL PONS, a sub-Aject of the King of Spain, residing in the city of Buffalo, county ofErie, State of New York, have invented certain new and usefulImprovements in Fiber-Cleaning Machines, of which the following is aspecification, reference being had therein to the accompanying drawings,in which- Figure 1 is a side elevation of the machine in position foroperating. Fig. 2 a side elevation from the opposite side showing themachine in position for transportation; Fig. 3 a front elevationthereof; Fig. 4 a rear elevat-ion; Fig. 5 a longitudinal verticalsectional View;- Fig. 6 a detail view of the means for securing theknives to the cleaning drum; Fig. 7 a detail sectional view of oueof thepresser plates; and Fig. 8 a detail view of the adjustable bearing ofthe cleaning drum shafts.

One of the many objects of this invention is to produce a machineespecially adapted to strip the fiber from long leaves, such as theab'aca (Manila hemp) planato (banana) pita, etc., and wherein the leafwill be fed into the machine longitudinally andwill be scraped Vso fromend to end.

Another object of the invention is to )rovide a machine wherein theleaves will be given an initial scraping and then a final scraping sothat the fiber is very clean when it is delivered from the machine.

A further object of the invention is to provide means whereby the leafwill be almost entirely fed through the machine in one direction andpartially or initially scraped, and will then be drawn back by the samefeeding means, the same scraping means serving as a final scraping meanswhen the direction of movement of the leaf is changed.

It is also the object of this invention to provide means whereby theleaf when it is first inserted in the machine will cause the feedingmeans tov rotate in the proper direction to feed the leaf to thecleaning drum, and whereby said leaf after a certain portion of it hasbeen cleaned will permit the automatic reversal of the feeding means,whereby the direction of movement of the leaf will be changed withoutchanging the direction of movement of the cleaning drum.

These are some of the most important objects of the invention. Otherequally important objects and advantages of the invention will appearhereinafter. O

surface of said drum are the clcaniiik Referring to the various partsbynumerals, 1 designates the framing of the machine, in the upper rearend of which is mounted a transversehorizontal driving shaft 2. On thisshaft outside of the vsupporting frame and near each end thereof isadjustably secured a large fly-wheel 3. These wheels are provided withcranks 4 by means of which they may be rotated'and the machine operatedwhen said wheels are made fast to the shaft 2 by set screws 4, Mountedon this shaft isa large sprocket wheel 5 over which runs a sprocketchain 6. This sprocket chain engages the sprocket wheel 7 rigidlysecured to a transverse drum carr r,ing shaft i NITEDsierrasiATENTf-FFC?" Patented sept. 22, 1908. v l

8. A drinn 9 is rigidly mounteion said shaf t between the sid-,c piecesof thel supporting frame, and projecting radiallyfrointhe kuvs 10, saidknives being suitably securedhto said drum and projecting beyond theperi `Alieiy thereof, as clearly shown in the draw1`gs`;\

Mounted in the frame forward of the cle 8 ing drum 9 are two transverseparallel shaf 11 which are located suitable distances apart and Ahaverigidly secured to them between the side frames of the machine twofeeding rolls 12. These rolls are formed with transverse parallel iibsand depressions, the rolls being so adjusted with respect to each otherthat the ribs of one roll engage the corre- I spending corrugations ofthe other roll; so that when said rolls are rotated they will grip theleaves between them and form a positive feeding means, incoiitradistinction to the feeding rolls which operate merely byfriction. Loosely mounted on each shaft 11 is a sprocket wheel 13 whichcarries one member of a clutch 14, the other member thereof beingadapted to be brought into enga-ge ment therewith by means which will beIieref inafter described, said sprocket wheel being caused to run fastor loose on the shafts 1 1 by said clutches.

In the forward upper end of the machine is mounted a pair of transversehorizontal smooth receiving rolls 15, the lower one of which is mountedon a shaft 16 journaled in rigid bearings. The upper roll is carried bya shaft 17 which is journaled in blocks yieldably mounted in boxes .1Sformed in the sides of the machine frame. In these boxes are arrangedcoil springs 19 which bear upon the journal blocks aiir normally hold tiem at the bottom of the boxes 1S, the two feeding Y rolls in thisposition of the box engaging each other as shown clearly in Fig. 3. Itwill thus with a. depending arm 22 which is loosely connected by meansof al pin 23 to a downwardly and rearwardly extending rock shaft 24which is mounted in bearings on the outer and groove.

be seen that the upper feeding roll is yieldably held in engagement withthe lower feeding roll. The shafts of these two rolls are gearedtogether by means of the gears 20 and 21, the teeth of said gears beinglarge enough to permit the upper receiving roll tohave a slight outwardmovement without disengag ing said teeth. One end of the shaft 17, theright hand end as shown in Fig. 3, is provided driven by a chain 27 fromthe drum shaft S,

and when the upper receiving roll 15 is in contact with the lowerreceiving roll the members of the lower Clutch 14 are in cn-' gagen'ientas shown in Fig. 3, andthe lower corrugated roll 12 is driven by thechain 27 while the upper sprocket 1,13 rims loosely on its shaft. YVhena leaf is inserted between the two receiving rolls 15; the upper roll isforced upward against the-, springs 19, causing the arin 22 to rockshaft 24 and thereby throw out the lower clutch and bring the members ofthe upper clutch into engagcment whereby the chain 27 will drive theupper sprocket wheel 13, the lower sprocket Wheel ruiming loosely on itsshaft. This movement of the clutches reverses the direction of rotationof the corrugated feeding rolls, as will be more fully hereinafterdescribed. ,y 4

The shaft of the upper corrugated feeding roll is mounted insuitable'jmirnal boxes which are yieldabl;v held in position by means ofsprings 2S whereby said roll may ield or move outward slightly toreceive the eaves. Below the lower receiving "roll 15 and at the forwardend of the machine is mounted a transverse horizontal roller 29 which isarranged close to and parallel with said roll. Over this roller isarranged a feed belt 30 which passes around the lower corrugated feedrolls 12 and receives `its motion therefrom, the direction of movementof said belt being reversed when the direction of rotation of t-liefeeding roll is reversed. The shafts of\ the feeding rolls 12 are gearedtogether by gears 31. as shown in Fig. 2, so that said rollsarepesitively driven one fiom the other` The chain 27 passes over theSmall sprocket wheel mounted on the transverse shaft 33, and oistheopposite end of said shaft is secured a sprbckct wheel 34 over whichruns a sprocket chain 35, said chain driving a. sprocket' wheel .'36mounted on the shaft of tief'lower receiving roll 15. The receivingrolls rotate in one direction at all times during the operation' of4 themmaehine.

In the lower part of .tlie'frame of themachine'forward of the firstcleaning wheel and below the same, is..niQunted a transverse shaft 37 onwhich is mounted a second clean#l ing drum 3S, said drinn carrying inits pcripherycleaningknivesf). Ononc end of the shaft 37 is securedasprocketwheel 40 over which runs the chain 27, said sprocketwheel andthe corresponding sprocket wheel on the shaft of the first cleaning drumbeing of the saine size, the chain being arranged to run' thereon insuch manner as to drive both cleaning drnins in the same direction. In

the frame forward of the second cleaning drum and sligh tly above. itare mount-cd two longitudinally corrugated feeding rolls 4l, the shaft42 of the upper roll being journaled in boxes 43 which .are yieldinglyheld in position by springs 44. The shafts of these rolls are connectedtogether by means of gears 45, and on the shaft of one of said rolls issecured a. sprocket wheel 46 over which rims a sprocket chain 47 saidchain being driven by a small s iaft 49. On this shaft is secured alarge gear 50 which meshes with the gear 31 secured to the lowertransverse shaft 11 of the upper set of corrugated feeding rolls. Thelower feeding roll 41 is much larger in di ameter lthan its co-actingroll so that when the end of the leaf is delivered to said rolls by thebelt 30 said end will be caught by the larger lower roll and carriedinward to the a curved presser plate 51 which is substan-V sprocketwheel 48 mounted on a transverse tially concentric to the cleaning drum.The

upper end of this presser plate is arranged so that the end f the leafon emerging from the feed iolls i .vill be received between said )lateand the cleaning drinn, and will then lie carried by the cleaning knivesalong said plate, said knives scraping the. leaf as it passes throughthe channel between the pla-te and the drum. The upper end of this plateis pivotally mounted upon end studs 52 and its lower end is adjustablysupported by screws 53. By means of the screws the presser plate maybeso adjusted as to secure the proper operation of the knives on theleaves.

The presser plate 54 is arranged forward 0f l the s econd cleaning wheeland is adapted to receive the leaf from the second'set of positivefeeding rolls 41; and this presser plate is provided wit-li adjustingscrews 55, its upper end being pivotall)v mounted upon end studs 56. VAtthe forward end of this belt 30 is arraged a depending guide lplate 57which receives the leaf from said be t and directs it to theJl feedi'olls 41, a screw 58 being provided byl'fwhich this guide plate may beadjusted to deliver the leaf at the proper point on the lower-largerfeed roll 41. i

The\ shafts of the cleaning "drums are mounted in movable journal boxes59 which are adapted Vto be adjust-ed by means of screws Gd to securethe proper relative positions of the cleaning knives and the presserplates. The cleaning knives are adjustably secured ingthe cleaningdrums. By reference to Figjx it will be seen that the knives are formedwith threaded extensions 61 by means of which they may be readilyadjusted in the drum. .Ylhe drums are each formed with inwaidlyel'vtending transverse enlargements 62 which are transversely channeledto receive the knives. Arranged \to bear against one side of each of theknives is a transverse wedge bar 63, one face ofhvhich extends inwardand away from the knife. Engaging this inclined face of the wedge\bar isa correspondingly inclined face of a bolt head 64, said bolt extendingthrough the enf largement 61 and being securely locked in y place by anut 65.` it will be readily seen that by clamping the bolt in lace thewedge bar is forced against the kni e and the knife readily clamped inthe channel formed in the cleaning drum. It will be noted that the headof the bolt and the wedge bar are below the periphery of the drum.

T he presser plates are formed with side flanges 66 as shown clearly inFig. 7 to prevent the fiber, or any portion ofthe leaf, escaping fromsaid plates at the sides thereof.

lheniachiiie at its forward end is sup orted on small transportingwheels 67 whicli mounted in the frame. When the machine is in itsoperative position it is supported Vat its rear end on legs 69 which arepivoted at 70 on the frame, and incline rearwardly. These legs areformed with extensions 71 which extend above the pivots and rest againstflanges 72 foi-ined on the frame. In this position the. weight` of therear part of the machine is sustained by the legs. lVhen it is desiredto transport the machine from place to place the legs are swung forwardon the pivots 70 and held up out o f o erating position by means of ahook 73 as. s iown .in Fig. 2. This permits iie machine to be lowereduntil the large tiy-wheels rest upon the ground and supportthe machine.These wheels are then permitted to run loose on the driving shaft byloosening the set screws 43j l/Vhenin this position the machine may beare secured on a transverse shaft 68 suitably readily moved from placeto place, the iiywheels and wheels 66 at the forward end of the machine,serving as transporting wheels.

The operation of the machine is as follows:-Oiie end of the leaf,preferably the thinner end, is Vintroduced between the smooth receivingrolls, forcing upward the upper roll, therexby through t-he arm 22 andthe rock shaft 24, throwinglthe upper clutch yoke 26 inward and bringinginto engagement the members of the clutc i 14 connect-ed to the uppersprocket wheel .13. The driving lower'corrugated feed roll 12 it willalso move Y to carry the leaf inward toward the first or primarycleaning drum. As the leaf is drawn inward b the smooth feed rolls, it'dro s down to t e belt 30 and b rie inward to the positive feed io s 12.By

it is car-f' these latter rolls the leaf is positively fed inward intothe channel, between the presser plate 51 and the first cleaning drum 9.This cleaning drinn rotates at a constant speed and iu the directionindicated by the arrow and scraples the pulpy matter from the leaf,leaving t e fiber uninjured and also carrying the fibers through thechannel formed by the presser plate, and causing the clean leaf toemerge from said channel at the rear end of said plate. The knives inthe cleaning drum and the presser plate are so adj usted that the fibersare left com Y aratively clean after the fiist scraping or c canino'operation; When the butt end of the leaf has passed between thereceiving rolls and dro ped to the belt 30, the upper receiving rollwill be moved inward b v the s rings 19 and the rock shaft 24 will bemover through its connection with the shaft of said ioll to disengagethe niembers of the u per clutch and to throw into engagement tli'emembers of the lower clutch.

, This will cause the lower sprocket wheel 13 lto rotate with itsshaftand the upper one to run loosely, thereby reversing the motion ofthe positive feed rolls and the belt 30. It will be noted that thisreversal of the motion of t-liese parts will take place before the butt'.end of the leaf has passed between the positive feed rolls. The resultof this is thatthe direction of movement of the leaf will be reversedaiid that the positive feed rolls will draw the clean leaf back throughthe channel between the presser-plate 51 and the first cleaning drum,and that as said cleaning,

drum continues its rotation that portion of the leaf will be againscraped, so that the iibeis after they have passe( the second timethrough said cleaning channel will be thoroughly cleaned. The belt 30will deliver the uiiscraped end of the leaf against the plate 57 Vbywhich it will be directed downward and Lio ' one-io nth the speed of the'first positive feed rolls so that a greater ort-ion oi the leaf will bedelivered to the be t 30 and by the belt 30 to the feed rolls 41, thanwill be fed by these isti-er rolls to the second cleaning drum. The ofthis will" be that the entire leaf will be scharged over the forward endof said :S0 when only about ono-fourth of it has been ied by the secondpositive feed rolls to the second cleaning' drum, the surplus leaffalling down in iront of the machine. it is obvious that the roll lt1of? the second reed rolls siii not support the surplus` lea-"f` that isdelivered to it by the belt 30-7 and that that portion of it whlch isnot i'ed to the second cleaningnieanswill naturally drop down in front othe machine. The purpose of this is to have the second cleaning drum actonly upon theirv part oi the leal" that was not acted upon by the firstcleaning drum, or a proximately so. fis-soon as the cleaned en( of theleaf hes irc ped from the belt 30 the thinner end or anotier leaf' isinserted between the receivnng rolls 15. thereby forcingupward the upperro'i and again reversing the direction oi roest-Len of the ieed rollsand belt 30, so that the new leaf will be carried inward to the positiveiced rolls 12 and be delivered to the rsa cleaning drum. It will benoted that this action will also reverse the direction of rotaicn of thesecond set oi" ositivc feed rolls el :and that instead o1e fee( ingV theleai` to the ser-.ond cleaning drum they will act to draw the portion sofed, back through the cleaning3 channel, said portion being a secondtime scraped. It will therefore, be seen that when the. leaf or Strickof fiber isiinally delivered si. the front ofthe machine it has.

been scraped twice throughout its entire lengthihout any ham-lling bythe operator excepi ze insert one end thereof between the receii'irrgFrolls, all subse uent operations being antonin-tic. It will a so bcnoted that the new leef may be inserted' between the receiving i" beforethe lil-st leaf has passed entirely through the machine so that aconsiderabe saving of time is effected.,

"This I have described what now consider a :freier-red form o? myinvention, it is manif s that many changes and modifications nisv bemade therein, and desire it unde toed that ll do not wish to be limitedy 55 to the exact form of' machine shown, but desire it understood thatsaid machine is merely illustrated.
